High Altitude Illness Flashcards
What is acclimitization
Acclimatization: compensatory response to acute hypobaric hypoxia, improves tissue oxygenation
- varies based on degree of hypoxic stress, individual capacities/factors
- increase ventilation, sympathetic activity, Hgb concentration, vascular endothelial growth factor
- we can’t acclimatize to rapid pressure changes
Describe the etiology of high altitude illness
Initial cause = hypobaric hypoxia which leads to relative fluid retention
Prevention = slow ascent
Describe the clinical presentation of acute mountain sickness
Describe the clinical presentation of high altitude cerebral edema (HACE)
Describe the clinical presentation of high altitude pulmonary edema (HAPE)
Describe the diagnostic testing for acute mountain illness
Describe the diagnostic testing for HACE
Describe diagnostic testing for HAPE
Describe the treatment for acute mountain illness
Describe the treatment for HACE
Describe the treatment for HAPE
